HERMAN O. WVILLITZ, OF JANESVILLE, WISCONSIN, ASSIGNOR OF ONE- HALF TO HENRY MULBERGER,

OF WATERTOVVN, WISCONSIN.

LINE-WIRE CLAMP.

Application filed October 17, 1903- To all? whom it may concern;

Be it known that I, HERMAN C. WILLITZ, a V citizen of the United States, and a resident of J anesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Line-VVire Clamps; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has especial reference to means for uniting without the use of solder the inside wire that enters a building to the outside line-wire of a telephone or telegraph system, so that a current of electricity may flow thereover; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accompanying drawings and subsequently claimed.

In the said drawings, Figure l is a view of my said device in operative position, said view being partly in side elevation and partly in section on the line 1 1 of Fig. 2. Fig. 2 is a plan view of the same, partly broken away; and Fig. 3 is a sectional view taken on the line 8 3 of Fig. 1. f

In the old way when the connection was made by solder at the point where the wire enters a building if a lineman desired to make a test he would open up this soldered connection, and then in the great majority of cases he would not have a soldering outfit with him, and hence to close the joint he would usually simply loosely twist the end of the inside copper wire around the end of the outside iron line-wire, which would result in a poor connection, which objection is entirely obviated by my present invention.

Referring by numerals to the drawings, 1 indicates the outside or line wire, which is usually of'iron, and 2 designates the inside or house wire, usually of copper and of less diameter, though of coursethe line-wire may be of copper, if desired. In practice the end of the inside copper wire 2 is freed from its in: sulated covering and wrapped around the linewire 1, as shown at 3, and then my clamp is applied, as shown in the drawings. This @PEGIFICATION forming part of Letters Patent No. 755,092, dated March 22, 1904.

Serial No. 177,406. (No model.)

' clamp is made of spring metal, preferably of thin flat spring-steel doubled upon itself, as shown, and with its ends removably united by a link, thus having an under portion 4:, which at' one end is wound around the link 5, as shown at 9, with a bend 6 at the opposite end, and anupper portion 7 which terminates in an upturned edge or lip 8, there being a transverse groove or bead 11 formed in the upper portion' (and, if desired, a corresponding groove or bead 10, as shown, in the under portion) adjacent to the bend 6 for the better reception of the wrapped wire, and when these parts are in place the link 5 is swung over and snapped to place against the upturned edge or lip 8 of the upper portion 7 and held in place by the spring action of said part.

On cable-poles where a piece of insulated copper wire is usually employed to connect the outside line-wire with the cable-wires it has been customary to make soldered connections; but my'clamps may here be used in place of solderwith great advantage, and here, as well as in house connections, my device is a great saving in time, as any ordinary lineman can quickly adjust the device to place, and it is always accessible when necessary to make a test, and then when the clamp is replaced the connection is just as good as before, and the trouble of soldering is wholly done away with, with its subsequent poor connection.

Having thus described my invention, what I claim as new, and desire-to secure by Letters Patent, is

1. A line-wire clamp, comprising a doubled spring-strip, having a movable link at one end, and an upturned edge or lip at. the other, for engagement with said link.

2. A line-wire clamp, comprising a doubled spring-strip, having a movable link at one end, and an upturned edge or lip at the other, and opposed transverse grooves or beads adjacent to the bend of said strip for the reception of the wires.

3. The combination with the outer line-wire of the inner house-wire, whose endis wrapped around said line-wire, and a spring-clamp the county of Milwaukee and State of Wisfolded over the thus-wrapped wire, and held consin,. in the presence of two witnesses.

tightly against the same whereby a positive r electrical connection is obtained Without the i HERMAN TILLITL' 5 use of solder. Witnesses:

In testimony that I claim the foregoing I H. G. UNDERWOOD, have hereunto set my hand, at Milwaukee, in HUGO FAHL.
